Abstract

A new and distinct cultivar of Osteospermum plant named ‘Duetisweka’, characterized by its compact, upright and mounded plant habit; freely branching growth habit; dense and bushy plant form; early and freely flowering habit; and daisy-type inflorescences with elongated oblong-shaped ray florets that are dark red purple in color.

Description

Botanical designation: Osteospermum ecklonis.
Cultivar denomination: ‘DUETISWEKA’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis and hereinafter referred to by the name ‘Duetisweka’.
The new Osteospermum plant is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the program is to create and develop new compact Osteospermum plants with uniformly mounded plant habit and numerous attractive inflorescences.
The new Osteospermum plant originated from a self-pollination in July, 2006 of a proprietary selection of Osteospermum ecklonis identified as code number Q05-4399-501, not patented. The new Osteospermum plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated self-pollination in a controlled greenhouse environment in Rheinberg, Germany in May, 2011.
Asexual reproduction of the new Osteospermum plant by terminal cuttings in a controlled environment in Rheinberg, Germany since June, 2011 has shown that the unique features of this new Osteospermum plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
Plants of the new Osteospermum have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duetisweka’. These characteristics in combination distinguish ‘Duetisweka’ as a new and distinct Osteospermum plant:
    • 1. Compact, upright and mounded plant habit.
    • 2. Freely branching growth habit; dense and bushy plant form.
    • 3. Early and freely flowering habit.
    • 4. Daisy-type inflorescences with elongated oblong-shaped ray florets that are dark red purple in color.
In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Osteospermum differ primarily from plants of the parent selection in ray floret color as ray florets of plants of the parent selection are bluish in color.
Plants of the new Osteospermum can be compared to plants of the Osteospermum ecklonis ‘Cape Daisy Lubango’, not patented. In side-by-side comparisons, plants of the new Osteospermum differed primarily from plants of ‘Cape Daisy Lubango’ in the following characteristics:
    • 1. Plants of the new Osteospermum are more compact than plants of ‘Cape Daisy Lubango’.
    • 2. Plants of the new Osteospermum had shorter leaves than plants of ‘Cape Daisy Lubango’.
    • 3. Inflorescences of plants of the new Osteospermum had larger and darker red purple-colored ray florets than inflorescences of plants of ‘Cape Daisy Lubango’.
BRIEF DESCRIPTION OF THE PHOTOGRAPH
The accompanying photograph illustrates the overall appearance of the new Osteospermum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum plant. The photograph comprises a side perspective view of a typical flowering plant of ‘Duetisweka’ grown in a container.
 DETAILED BOTANICAL DESCRIPTION
The aforementioned photograph, following observations and measurements describe plants grown during the spring in 12-cm containers in a glass-covered greenhouse in Rheinberg, Germany and under cultural practices typically used in commercial Osteospermum production. During the production of the plants, day and night temperatures averaged 18° C. and light levels averaged 4,500 lux. Measurements and numerical values represent averages for typical flowering plants. Plants were pinched one time about three weeks after planting and were 13 weeks old when the photograph and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
